9.4 Cumulative Translation Account Overview
Under ASC 830-30, all financial statement elements must be translated from the functional
            currency to the reporting currency by using a current exchange rate, which ASC
            830-30-45-4 defines as “the rate as of the end of the period covered by the financial
            statements or as of the dates of recognition in those statements in the case of
            revenues, expenses, gains, and losses.” For practical reasons, ASC 830 permits the use
            of weighted-average exchange rates or other methods that provide a reasonable
            approximation of the rates in effect on the date of recognition.
        The following is a summary of the exchange rates used in the translation process:
        9.4.1 Recognition of Deferred Taxes for Temporary Differences Related to the CTA
As stated above, under foreign currency guidance in ASC 830, assets,
                liabilities, revenues, expenses, gains, and losses of a foreign subsidiary whose
                functional currency is the local currency are translated from that foreign currency
                into the reporting currency by using current exchange rates. Translation adjustments
                recognized as part of this process are not included in the determination of net
                income but are reported as a separate component of shareholders’ equity (the CTA).
                After a change in exchange rates, the translation process often creates basis
                differences in amounts equal to the parent entity’s translation adjustment because
                it changes the parent’s financial reporting amount of the investment in the foreign
                entity but the parent’s tax basis in that entity generally does not change.
            A DTA or DTL may be required when an entity recognizes translation
                adjustments as a result of an exchange rate change if the parent entity is accruing
                income taxes on its outside basis difference in a particular investment (note that a
                CTA can be recorded on both the capital and undistributed earnings of the
                investment, as illustrated in the example below). However, ASC 830-30-45-21 states,
                in part, that if “deferred taxes are not provided for unremitted earnings of a
                subsidiary, in those instances, deferred taxes shall not be provided on translation
                adjustments.” In other words, if all or a portion of the earnings are not
                indefinitely reinvested and the related temporary differences will reverse within
                the foreseeable future (i.e., the earnings will be repatriated to the parent),
                translation adjustments associated with such unremitted earnings will affect the
                deferred taxes to be recorded. Conversely, if the earnings are indefinitely
                reinvested and the requirements in ASC 740-30 for not recording deferred taxes on
                unremitted earnings of a foreign subsidiary have been met, deferred taxes on the
                translation adjustments are similarly not recorded.
            Example 9-7
                                Assume that Entity X, a calendar-year U.S. entity whose
                                        reporting currency is USD, has a majority-owned subsidiary,
                                        S, located in the United Kingdom, and that S’s functional
                                        currency is the British pound. In addition, assume that as
                                        of December 31, 20X1, S’s net assets subject to translation
                                        under ASC 830 are 1,100 British pounds, the exchange rate
                                        between USD and the British pound is 1 to 1, X’s tax basis
                                        in S’s common stock is $1,000, and S had $100 in unremitted
                                        earnings for 20X1. Further assume that, in a manner
                                        consistent with ASC 830-10-55-10 and 55-11, the calculation
                                        of $100 in unremitted earnings was based on “an
                                        appropriately weighted average exchange rate for the
                                        period,” which was also 1 to 1.
                                    Moreover, assume that on December 31, 20X2, S’s common stock
                                        subject to translation is unchanged at 1,000 British pounds,
                                        S’s undistributed earnings for 20X2 are 200 British pounds
                                        (the total undistributed earnings as of December 31, 20X2,
                                        are 300 British pounds), and the weighted-average exchange
                                        rate during the year between USD and the British pound
                                        remained at 1 to 1. As of December 31, 20X2, however, the
                                        exchange rate is 2 to 1. Thus, X’s investment in S is
                                        translated at $2,600, and the CTA account reflects a $1,300
                                        pretax gain. Entity X has the intent and ability to
                                        indefinitely reinvest undistributed earnings of S (inclusive
                                        of the CTA). Thus, in accordance with ASC 740-10-25-3(a)(1),
                                        no DTL is recognized on the portion of the outside basis
                                        difference related to the undistributed earnings of S
                                        (inclusive of the CTA). Further, in accordance with ASC
                                        830-30-45-21, no deferred taxes are provided on the
                                        translation adjustments related to the common stock.
                                    However, if X does not have the intent and
                                        ability to indefinitely reinvest S’s earnings (although X
                                        believes that its original investment in S is considered
                                        indefinite under ASC 740-30), a DTL should be recorded for
                                        the portion of the outside basis difference related to
                                        unremitted earnings, including the $300 translation
                                        adjustment on the earnings (on the basis of a weighted
                                        average of exchange rates for the period). However, X would
                                        not have to record a DTL for the $1,000 of CTA related to
                                        the 1,000 British pounds of common stock if the initial
                                        investment is indefinitely reinvested.
                                    Note that after the enactment date of the
                                        2017 Act, undistributed earnings may not give rise to a U.S.
                                        taxable outside basis difference because such earnings
                                        are/were immediately includable in an entity’s U.S. taxable
                                        income (whether as a result of (1) the entity’s deemed
                                        repatriation tax (see IRC Section 965) or (2) deemed
                                        repatriation as a GILTI inclusion or Subpart F inclusion in
                                        the year earned) or are eligible for the IRC Section 245A
                                        dividends received deduction when the entity is measuring
                                        the U.S. DTL. However, there may still be a future tax
                                        impact related to foreign currency fluctuations (see IRC
                                        Section 986(c)); therefore, if X is not indefinitely
                                        reinvested in S, the $1,300 gain recognized in CTA may
                                        represent a taxable temporary difference.
                                When a DTL or DTA related to a parent entity’s cumulative foreign
                currency translation adjustments is recognized, the tax consequences of foreign
                currency exchange translations are generally, in accordance with the intraperiod
                allocation rules, reported as a component of the CTA account in accordance with ASC
                740-20-45-11(b).
            See Chapter 6 for a detailed discussion of intraperiod allocation.
